Abstract

A stringed musical instrument has a molded sound box and neck where the sound box is formed of between 20% to 60% carbon fibers, or other suitable fibers, and a polymeric resin or binder. The composition of materials utilized in the sound box is selected to increase stiffness and to control the tone of the instrument. The sound box includes an adjustable attachment mechanism having a pivot which is used to secure the neck to the sound box. The sound box includes a molded bracing structure having a plurality of braces and a molded bridge having a plurality of pockets which are used to enhance the structure for the sound box and provide a desired tone quality for the stringed instrument. The neck may include a molded neck insert and a molded fingerboard which are used to enhance the stiffness and stability of the neck.

First claim

I claim:

1. A neck for a stringed musical instrument, said neck comprising:
a fiber compression or injection molded neck section having a headstock section and a heel section;
a fiber injection molded fingerboard engaged to said neck section, said fingerboard comprising a molded pocket; and
at least one fiber insert engaged to said fingerboard and disposed in said molded pocket, said at least insert being constructed and arranged to enhance stiffness and stability of said neck section.

2. The neck according to claim 1 , wherein said neck section is hollow and at least one fiber neck insert is disposed in said hollow neck section.

3. The neck according to claim 1 , wherein said neck is connected to a sound box comprising a soundboard, a bracing structure, a side wall, and a bottom wall.

4. The neck according to claim 3 , further comprising an injection or compression molded bridge engaged to said soundboard, said bridge comprising a lower side comprising a plurality of pockets.

5. The neck according to claim 1 , said at least one fiber insert comprising carbon fiber.

6. The neck according to claim 1 , said fiber injection molded fingerboard comprising a first side and an opposed second side, the second side contacting said at least one fiber insert, said first side comprising frets.

7. A neck for a stringed musical instrument, said neck comprising:
a fiber compression or injection molded neck section having a headstock section and a heel section;
a fiber injection molded fingerboard engaged to said neck section; and
at least one fiber insert engaged to said fingerboard, said at least insert being constructed and arranged to enhance stiffness and stability of said neck section;
wherein said neck is connected to a sound box comprising a soundboard, a bracing structure, a side wall, and a bottom wall;
further comprising an adjustable attachment mechanism constructed and arranged to adjustably attach said neck to said sound box in a vertical direction and in a horizontal direction.

8. The neck according to claim 7 , said attachment mechanism comprising a pivot positioned between the heel section and the sound box.

9. The neck according to claim 7 , said adjustable attachment mechanism comprising a first fastener arranged to provide adjustment about a first axis.

10. The neck according to claim 9 , said adjustable attachment mechanism comprising a first adjustment screw arranged to provide adjustment about a second axis, the second axis orthogonal to the first axis.

11. The neck according to claim 10 , said adjustable attachment mechanism comprising a second fastener, said first fastener and said second fastener aligned upon said second axis.

12. The neck according to claim 10 , said adjustable attachment mechanism comprising a second adjustment screw, said first adjustment screw and said second adjustment screw oriented on opposite sides of the second axis.

13. A neck assembly for a stringed musical instrument, said neck assembly comprising:
a neck section comprising a headstock and a heel;
a fingerboard engaged to said neck section, said fingerboard comprising a pocket; and
a stiffening fiber insert positioned in said pocket and engaged to said fingerboard.

14. The neck assembly of claim 13 , said stiffening fiber insert comprising carbon fiber.

15. The neck assembly of claim 13 , said fingerboard comprising a first side and an opposed second side, the second side contacting said stiffening fiber insert, said first side comprising frets.

16. The neck assembly of claim 13 , the neck section comprising a cavity and a neck stiffener oriented in the cavity.

17. The neck assembly of claim 13 , said headstock comprising a cavity and a fiber-reinforced headstock insert oriented in the cavity.

18. The neck assembly of claim 17 , said headstock comprising a headstock veneer.

19. The neck assembly of claim 13 , arranged for attachment to a soundbox and comprising adjustable attachment mechanism comprising a pivoting mount and a fastener.

20. The neck assembly of claim 13 , arranged for attachment to a soundbox and comprising adjustable attachment mechanism comprising a fastener arranged to provide adjustment about a first axis and an adjustment screw arranged to provide adjustment about a second axis, the second axis orthogonal to the first axis.
